Error Message screencap

Got this error running Conan on MacOS, trying to build a package that required opencv 4.5.0 to build from source.

On first glance it looks like OpenCV is messed up or maybe conan but if I look up past all the red text I can see the real original cause of the issue. The red text is just a cascading consequence of this original error message.

For this reason, I do advise not to stop reading a log at the first error message you find, but instead to try to see if there is some cascading effect and to see…

some rainbow bash for the kewl colors

A for loop is a relatively simple concept, but I wanted to break down the syntax here because under the hood, bash is very much, and I cannot exmphasize this enough, not C. I do try to see what’s happening under the hood though so that when I copy paste from StackOverflow and it doesn’t work, I can actually troubleshoot.

You can loop through arrays in bash like this

array=(thing1 thing2)for i in "${!array[@]}"; do
echo ${array[$i]}

If you want to iterate through pairs, an easy way to do that would be something like this:

xvalues=(x1, x2, x3)

Error Message from Git Bash:

bash: pip: command not found

Error Message from DOS command line:

'pip' is not recognized as an internal or external command,
operable program or batch file.

If you’ve literally just installed Python, you may want to rerun your Python installer and make sure you check this box:

Here’s how to fix this:

Github deprecated logging in with a user name and password so what you need to do is to create a “personal access token”

The cover

This book is about happy chemicals and how to make your brain emit them. It is a happy-chemical centric strategy book.

Difficulty: not difficult

Basic Premises: Happiness is a chemical reaction, so be a good chemist. There are 4 happy chemicals: Serotonin, Dopamine, Ocytocin, and Endorphin.

Potentially Controversial Takes: This book references the theory of evolution a lot.

My Favorite Passage:

Your cortex is always making predictions about future pain and future rewards. But anticipated rewards don’t always materialize, which is another source of cortisol. Your cortex can…

Windows 10 comes with an application called “Remote Desktop”

You don’t have to pay for it.

You can connect to any machine you know the IP address for and the username and password credentials for using Windows Remote Desktop.

You don’t have to connect to another Windows machine, you can connect to another Ubuntu (or whatever Linux flavor) machine, but, you will need to setup something called xrdp on the Linux machine first.

  1. Open a terminal
  2. Enter these commands
sudo apt-get update sudo apt-get install xrdp sudo apt-get install xfce4 #Optional stuff sudo apt-get install xfce4-terminal sudo apt-get install gnome-icon-theme-full…

I use this trick all the time.

Finding a convenient and handy file renamer I guess wasn’t that fruitful, but I have used this python trick more times than I…
